Cycles: Split vectorized types into separate files

The final goal to reach is to make vectorized types much easier to maintain
and the previous design had following issues:

- Having all types and methods implementation made the source file rather
  bloated and unfun to navigate in.

- It was not possible to quickly glance available API for the type you are
  interested in.

- Adding more vectorization types will bloat the file even more, making
  things even more tricky to follow.
